Few active filters on the market offer bandwidth higher than 2MHz. Yet today’s new generation broadband communication receivers push several to tens of MHz, requiring very good noise and distortion performance. Additionally, I/Q channel or multichannel receivers have tight matching requirements that are extraordinarily difficult to meet. For the most part system designers must resort to discret...

Sensory systems are faced with the task of extracting behaviorally relevant information from complex sensory environments. In general, sensory acquisition involves two aspects: the control of peripheral sensory surfaces to improve signal reception and the subsequent neural filtering of incoming sensory signals to extract and enhance signals of interest. The electrosensory system of weakly elect...

To develop an advanced battery estimation unit for electric vehicles application, the state-of-charge (SoC) estimation is proposed with an unscented Kalman filter (UKF) and realized with the RTOS lCOS-II platform. Kalman filters are broadly used to deploy various battery SoC estimators recently. Herein, an UKF algorithm has been employed to develop a systematic adaptive SoC estimation framework...

The recent trends show the interconnection of PV system with electric grid. With this configuration issue harmonics comes into existence. mounting figure power-electronic instruments has formed considerable impression on power-quality supply. Harmonics deformations have conventionally been handled amid application passive-LC filters. Active Filter emerged as a good substitute for passive filter...

BACKGROUND Different target-filter combinations in computed radiography have different impacts on the dose and image quality in digital radiography. This study aims to evaluate the mean glandular dose (MGD) and modulation transfer function (MTF) of various target-filter combinations by investigating the signal intensities of X-ray beams. METHODS General Electric (GE) Senographe DMR Plus mammo...

This thesis investigates movement of an electric wheelchair as a wheeled mobile robot (WMR) with a battery rechargeable through regenerative braking.The WMR has two wheels, each of which can propel or brake...

For imaging faint exoplanets and disks, a coronagraph-equipped observatory needs focal plane wavefront correction to recover high contrast. The most efficient correction methods iteratively estimate the stellar electric field and suppress it with active optics. The estimation requires several images from the science camera per iteration. To maximize the science yield, it is desirable both to ha...
